Storage condition:

Storage in a 50% charged state (Do NOT storage at fully charged state; Over long storage periods batteries should be cycled every 90 days, The method is to do a charge-discharge cycle with standard method. (Under normal storage conditions, long time storage can lead to decrease of capacity and cycle life, it will be caused more decreasing of the capacity and the cycle life if the storage condition out of the normal condition.)

Cycle Life(for cell):

Charge: 0.5C constant current charge to 4.2V followed by 4.2 V constant voltage charge to cut-off current ≤ 0.01C  

Discharge: 0.2C constant current discharge to cut-off voltage ≤ 2.5V

Discharge capacity of 301th cycle≥80%
